The operation of perorally placing contractive anvil is relatively simple in the surgery, the possibility of esophageal injury in the operation process is greatly reduced, in the stapling process, the anvil handle is capable of automatically triggering the control switch at the anvil handle side in the process of being inserted into the circular stapler, and the interference of a control guide wire in the stapling process is effectively avoided.
Description
Technical field
This utility model relates to a kind of surgical stapling utensil, especially relates to the oral delivery nail anvil device that a kind of automatic control is shunk.
Background technology
Current, for the minimally invasive surgery of the reconstruction of digestive tract such as the esophagus normal oral delivery nail anvil device of using that coincide, existing oral delivery nail anvil device comprises nail anvil top, nail anvil handle, guiding tube and control seal wire.Become possibility although existing oral delivery nail anvil device coincide the reconstruction of digestive tract minimally invasive surgery, still have following inconvenience in process of clinical application:
1) diameter of nail anvil consistent with the anastomat diameter (more than or equal to 2.5cm) stops because generally there is tracheal intubation in oral cavity in art, so in art, per os is inserted diameter and entered esophagus operation difficulty relatively more than or equal to the nail anvil of 2.5cm;
2) in art, per os is inserted diameter and is entered esophagus more than or equal to the nail anvil of 2.5cm, when introitus oesophagi arrives anastomotic position, easily causes Esophageal mucosa injury;
What 3) in art, the control nail anvil shrank is to complete by controlling seal wire, and in art, operation bothers relatively, and brings certain interference in art in actual anastomosis procedures.
Chinese patent CN1252255 discloses a kind of surgical tubular anastomosing device, realize that the nail anvil position adjusting mechanism has the speed regulatory function, the clamping degree of anastomosis staple after all critical positions that indicating mechanism can indicate nail anvil to move relative to nail barrel can indicate again anastomosis staple to be shaped, insurance institution is only just allowing firing handle to be pulled the trigger when the tissue that coincide reaches the scope of the grip thickness that is fit to identical operation, being suitable for especially coincide is positioned at the digestive organ in human body deep or the digestive organ of Microendoscopic coincided with human body, the suitable especially disposable surgical tubular anastomosing device cheaply of producing on a large scale on streamline also.
Chinese patent CN2461494 discloses a kind of surgical tubular anastomosing device, before the operation that coincide is carried out and during execution, and rigid attachment between the locating rod of nail anvil and anvil pull rod; After the operation that coincide was completed, nail anvil just can roll rotation, and the nail anvil of being convenient to roll after rotation withdraws from from more small-bore anastomotic stoma, to avoid tearing anastomotic stoma.Wherein most of parts are made by stamping parts, moulding and the pipe of structure and simple shape.Being suitable for especially coincide is positioned at the digestive organ in human body deep or at Microendoscopic coincide digestive organ, also suitable especially disposable orthochoanitic or the curved neck formula surgical tubular anastomosing device cheaply produced on a large scale on streamline.
Summary of the invention
Above-mentioned shortcoming for current oral delivery nail anvil device existence, the oral delivery nail anvil device that provides a kind of automatic control to shrink are provided the purpose of this utility model.
This utility model is provided with collapsible nail anvil and controller, described collapsible nail anvil is comprised of nail anvil top, collapsible and nail anvil handle, establish at least 3 for collapsible, the nail anvil top is connected with the nail anvil handle, the nail anvil handle is hollow tubular, the external guiding tube of nail anvil handle end, and nail anvil handle one side is provided with the gauge tap hole, the afterbody of nail anvil handle is provided with the anastomosis ring applicator draw-in groove, and the anastomosis ring applicator draw-in groove is used for the stationary annular anastomat; Described controller is provided with control spring, control stick and gauge tap, control spring is located at the front end of control stick, control stick is positioned at the nail anvil handle, controls the contraction of collapsible nail anvil, and gauge tap is located at the tail end of control stick and is passed the gauge tap hole of being located at nail anvil handle one side.
The utlity model has following outstanding advantages:
1) in art per os to insert the operation of collapsible nail anvil relatively simple;
2) because collapsible nail anvil can shrink, collapsible nail anvil diameter can contract and cause 0.5cm, and in operating process, the esophageal injury probability reduces greatly;
3) this utility model is controlled the contraction of collapsible nail anvil by controller, and in the process of coincideing, the nail anvil handle triggers the gauge tap of nail anvil handle side automatically in inserting the anastomosis ring applicator process, has effectively avoided controlling in the anastomosis procedures interference of seal wire.

The specific embodiment
Referring to Fig. 1 ~ 6, this utility model embodiment is provided with collapsible nail anvil and controller, described collapsible nail anvil is comprised of nail anvil top 11, collapsible 12 and nail anvil handle 13, establish 3 for collapsible 12, nail anvil pushes up 11 and is connected with nail anvil handle 13, and nail anvil handle 13 is hollow tubular, the nail anvil handle 13 external guiding tubes of end, nail anvil handle 13 1 sides are provided with gauge tap hole 131, and the afterbody of nail anvil handle 13 is provided with anastomosis ring applicator draw-in groove 132, and anastomosis ring applicator draw-in groove 132 is used for the stationary annular anastomat; Described controller is provided with control spring 31, control stick 32 and gauge tap 33, control spring 31 is located at the front end of control stick 32, control stick 32 is positioned at nail anvil handle 13, control the contraction of collapsible nail anvil, gauge tap 33 is located at the tail end of control stick 32 and is passed the gauge tap hole 131 of being located at nail anvil handle 13 1 sides.
Operational approach of the present utility model is as follows:
1) per os inserts guiding tube and connected collapsible nail anvil, and collapsible nail anvil is delivered to esophageal stump, causes external from thoracic wall or stomach wall handle hole the guiding tube end;
2) cut off guiding tube and nail anvil handle junction, remove guiding tube, esophageal stump is fixed in the nail anvil handle with the capable purse string suture of purse wire and knotting;
3) insert anastomosis ring applicator at the handle hole of thoracic wall or stomach wall, the nail anvil handle is inserted in the hole clipping at anastomosis ring applicator center, automatically trigger the gauge tap of nail anvil handle side, make the collapsible nail anvil expansion of contraction state be the umbrella nail anvil.Rotary annular anastomat end control loop makes nail anvil be contracted to the anastomosis ring applicator top and closely be connected with it, excites anastomosis ring applicator, completes identical.And move anastomosis ring applicator and nail anvil.
